What is it? Is there a keyword for it so I can look it up? All I got was
this error page from Ebay:

"The item you requested (7909446934) is invalid, still pending, or no longer
in our database. Please check the number and try again. If this message
persists, the item has either not started and is not yet available for
viewing, or has expired and is no longer available."

 

Try this:

this is actually the original one I wanted to post

Well, wish I could help you, but I got nothing for both of those "tinyurl"
pages, prolly cuz I have high security on my pc & those pages (not Ebay's,
though) come up as "restricted sites" on my IE (browser).
Sorry---

it reminds me of the thing that you could plug into a wall outlet and "turn
your whole house into a giant TV antenna."

I would not waste my money on this.
It's a device(resistor) to alter the O2 sensor's input to the ECU to give
"more performance".

A cold air intake would give better results.I bought my Bomz CAI off
Ebay,$60 postage included.

it's the tornado fuel saver, and if it worked for ,
manufacturers would be using them in production.

i just saw the other url. that's an o2 sensor resistor, forces it
into closed loop. unfortunately the ecu doesn't know the real air fuel
mix at that point. if it leans out you buy an engine.

That would be OPEN loop,when the ECU goes by a preprogrammed map.
(no feedback corrections)

Closed loop is where the ECU uses feedback from the O2 sensor to correct
the mixture,"closing the loop".
(O2 sensor detects lean/rich condition,ECU applies correction[more
fuel/less fuel],then O2 sensor then reads optimal,= a correction loop)

putting a resistor in tells the ecu what the 02 level is. thereby
holding it in closed loop. ever watch one with a scan tool? i have,
and they stay in closed loop once the coolant sensor says the engine
is warm.

You misunderstand what the term "closed loop" means. Closed loop is where
feedback from a sensor is used to generate an opposite response from the
controller,thus bringing the sensor back to 'neutral',maintaining the
closed loop. When you fix(replace) the sensor with a resistor,you have
broken the feedback loop(thus "open loop").The controller gets a fixed or
simulated sensor input and cannot bring the system back to stochiometric.

Now if the resistor goes in series with the O2 sensor,then it offsets the
sensor output,giving a bias.

i don't misunderstand, i've watched these on a live data list, once
the system goes closed loop, it take whatever the o2 reading is and
adjusts fuel trim, both short term and long term. the o2 input is not
required for the ecu to go into closed loop.

The URL above does not work.

Are you referring to either of the other two URLs that the original poster
(Lattes) gave? Namely:

http://tinyurl.com/2vy2r which says, among other things, "This is a resistor
that will plug into your AIT (air intake temp) sensor and modify your AIR/Fuel
ratio and slightly change your engine timing to run stronger and with increased
power."

http://tinyurl.com/2bt6f a.k.a. an "intake twister."

If you're referring to the device at Ebay auction site http://tinyurl.com/2vy2r
, then this device modifies the air intake temperature output signal to the ECU.
This signal causes the ECU to modify the fuel injector basic discharge duration.
See http://tinyurl.com/22d46 for more info.

The AIT sensor signal with the ECU comprises an open loop. That is, air intake
temperature changes, the AIT sensor signal changes, and the ECU reads the
changed AIT sensor signal. The ECU then commands a different fuel injector
discharge. There's no feedback to tell the ECU whether it correctly adjusted the
fuel injector discharge in response to the changed AIT.
